Abstract: Tracked vehicles, such as earthmoving and military vehicles, designed for mobility over rough terrains impose a severe ride environment. Prolonged exposure to such low frequency and large amplitude vibration can lead to driver discomfort, physiological damage, inefficient performance and thus reduced mobility performance. Ride characteristics of a military tracked vehicle are analysed via suspension, track tension, and track-terrain interactions. Ride response characteristics of nonlinear vehicle model are evaluated for stochastic excitations, arising from random terrains such as Belgian pave, ploughed field, pasture and MVEE course. Ride quality of the tracked vehicle is assessed in terms of average absorbed power associated with vertical and horizontal ride vibrations transmitted to the driver.
